SPECIFICATION forming part of Letters Patent No. 685,891, dated November5, 1901. Application filed April 29, 1901. Serial No. 58,063. (Nospecimens.)

To all whom it may concern.-

Be it known that I, RICHARD BEA'UCHAMP WHEATLEY, engineer, residing atNo. 115 Hungerford road, London, England, have invented a certain newand useful Improvement in the Manufacture of Metallic Alloys; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to the productionof metallic alloys; and its objectis to produce an alloy having an appearance closely resembling that ofgold. i

In carrying my invention into effect I first make an alloy'which I callthe base metal or base alloy, to which I add varying proportions ofadditional alloys. The base metal .1 form as follows: copper, sixty-sixparts, by

weight; zinc, fifty parts, by weight. To this base metal I add alloys ofother metals to form a perfectly homogeneous and fine-colored alloy.These metallic alloys I number 1, 2, 3, and 4:.

No.1 alloy is formed by melting eighty parts, by Weight, copper; twentyparts, by weight, manganese.

No. 2 alloy is formed by melting fifty parts, by weight, nickel; tenparts, by weight, tin; forty parts, by weight, copper.

No. 3 alloy isgformed by melting eighty parts, by weight, copper; twentyparts, by weight, aluminium.

No. 4; alloy is formed by melting fifty parts, 3 5

by weight, tungsten; fifty parts, by weight, 1ron. i

As an example of proportions I take one hundred and sixteen parts ofbase metal-viz. copper and zinc of N o. 1 alloy, five parts; No. 40

2 alloy, two parts; N0. 3 alloy, twenty parts; No. etalloy, four parts.

I claim--- V An alloy consisting of one hundred and sixteen parts of abase alloy composed of sixtysix parts c0 er and fifty parts zinc, fiveparts of an ad ltional alloy (No. 1) composed of eighty parts copper andtwenty parts man ganese, two parts of an additional alloy (No.

2) composed of fifty parts nickel, ten parts tin and forty parts copper,twenty parts of an additional alloy (N0. 3) composed of eighty partscopper and twenty parts aluminium, and four parts of an additional alloy(No. 4)

parts iron.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
